WebBased on a modified integrating sphere, it measures total reflectance at seven sub-bands in the 300-2500nm spectral regions. Total, diffuse, and specular reflectance is reported for the data at 20 degrees incidence. A total of twenty-one data points are produced during a single data acquisition cycle. WebA reflectometer is usually calibrated to tell you what a stone "most likely" is. For example, if you're looking at a ruby , a reflectometer will quickly tell you if the gem is not corundum. However, that is far from what you need for positive gem identification. Beware of Inaccurate Results Reflectometers are also notoriously inaccurate. how many contestants are in ridonculous race
